Ok, dufus....Hiroshima. Nagasaki. How many "innocent" children do you imagine there were there? Did it take a brain surgeon to figure it out? Or just a few useless American soldiers doing what they told?
It was a foregone conclusion that the United States was going to invade Japan and physically defeat it without consideration of the cost, in either US lives or Japanese lives. It was anticipated that there would be in excess of one million American casualties, and this was not a deterrent.
So, please tell us what your estimate is of the number of Japanese that would be killed when the United States invaded Japan and physically crushed the country.
10 million? 20 million? 30 million?
Then, compare that to the number of people killed by the two bombs that convinced Japan to surrender and end the war.
Well? How many Japanese lives were saved by the use of the two bombs?
... it's a simple arithmetic problem, dufus. What's your answer?
